I got hot temp warnings at a track day so here is what I found



You need to lift the a/c condensor off the coolant radiator to separate them & get some working space.

I am thinking cleaning this is good for a 10 deg or so drop in max temp which should keep the warning light on the dic off.

It was a 90 deg plus day & humid & shifty track so lots of high rpm.

The below pic is a fastener that I could not get back together, it holds the plastic shroud to an alum tab on the radiator on the other side (of the pic).

Need help if you guys figured out a work around on this, I think at high speed I need to have this fastened, it's not an issue off track.



The last clip secures the elec connector to the maf & it's cracked/broken, can you get these anywhere?



Thanks if you can help

Throw away the pain in the *** shroud clip. Not needed.
To clean radiator lay it flat on a flat surface and tilt it up from the top or bottom a couple inches then let go. That will dislodge the majority of the debris.

get a screen for the intake after reinstalling it the bottom breathers work just like a vacuum cleaner
that will cure most of the problem

Remove the airbridge and it's electrical connectors. Pull the top shroud off the radiator by removing the 4 bolts. Tilt the AC condensor forward and blow all the crap out with a spray nozzle like the one below. Order on line or at your local parts store - about $20. Then tilt the radiator forward, slide fans out of their mount and blow the radiator out. Reassemble. You will have about half a bucket full of junk to sweep up off the garage floor. Do it once a year.

Would a pressure washer with the wide fan tip do just as well or even better? Don't have an air compressor.

Might work but stay back and use low pressure the fins and tubes are none too sturdy.
Harbour freight has cheap air compressors.

I did not try to separate the fans from the radiator. Do they clip in/out same as the condensor?

Jason

Just pull it, to clean it.

How much more is there past the point where I had it spread open?

Just 2 hoses? Are there more fasteners (nuts/bolts) that hold it in?

Never had it out all the way, but I'm sure there is more crap in there to clean.

The plastic fan housing just slides down into two metal hooks/brackets on the radiator bottom. Lift it up and then slide back. Got to move them back to adequately get to all areas of the radiator. Just working through fan openings will miss a lot of area.

That is what a radiator shop did to clean my Ron Davis radiator that got clogged with speedy dry it picked up from the track after some guy oiled down two miles of WGI. First he got out a bunch of the stuff using a welding rod he filed down to a point then he took the radiator and dropped it from about a foot or so. When he picked it back up there was a large pile of dirt laying on the floor. He repeated this process until dirt stopped coming out of the radiator.

I am going thru the same issue as you but I have a C6Z06 so I'm not sure how similar the setups are. I think its pretty similar with the ac condenser sitting in front of the radiator with a shroud over them. On the C6 if the shroud is not seated right air will pass by without going through the cooler. Not sure if this applies to your bottom breather.

Good luck. I am also going to run more water, less antifreeze and add some Water Wetter.

Just go to Sears and get their small $100 air compressor...tiny...portable....and does great for 99% of what you need one for.

I'm with trackboss....REMOVE it, then gently drop if forward so that the inertia carries much of the debris out. Compressed air or a water stream (from the rear) will work some, but inertia works best.

Thanks all, how about that little clip, where to get?

I flogged it Sat/sun autox & no issues whatsoever temp wise.

Side bar: worn out a6's still stick pretty good (well enough to beat an Elise anyway).

You might want to try Casper's Electronics:

They seem to have a lot of automotive electrical connectors and harnesses.

Great, I will browse around.



I talked to their tech guy & he said it's a "secondary lock" for the connection & used during initial production to visually show that the connection is "made" but is unnecessary so long as the primary lock is holding.

They are sold out but I found it for $8.24, can this be right??
